Object types: SSLSocket -- subtype of socket.socket which does SSL over the socket Exceptions: SSLError -- exception raised for I/O errors Functions: cert_time_to_seconds -- convert time string used for certificate notBefore and notAfter functions to integer seconds past the Epoch (the time values returned from time.time()) fetch_server_certificate (HOST, PORT) -- fetch the certificate provided by the server running on HOST at port PORT. No validation of the certificate is performed. Integer constants: SSL_ERROR_ZERO_RETURN SSL_ERROR_WANT_READ SSL_ERROR_WANT_WRITE SSL_ERROR_WANT_X509_LOOKUP SSL_ERROR_SYSCALL SSL_ERROR_SSL SSL_ERROR_WANT_CONNECT SSL_ERROR_EOF SSL_ERROR_INVALID_ERROR_CODE The following group define certificate requirements that one side is allowing/requiring from the other side: CERT_NONE - no certificates from the other side are required (or will be looked at if provided) CERT_OPTIONAL - certificates are not required, but if provided will be validated, and if validation fails, the connection will also fail CERT_REQUIRED - certificates are required, and will be validated, and if validation fails, the connection will also fail The following constants identify various SSL protocol variants: PROTOCOL_SSLv2 PROTOCOL_SSLv3 PROTOCOL_SSLv23 PROTOCOL_TLS PROTOCOL_TLSv1 PROTOCOL_TLSv1_1 PROTOCOL_TLSv1_2 The following constants identify various SSL alert message descriptions as per http://www.iana.org/assignments/tls-parameters/tls-parameters.xml#tls-parameters-6 ALERT_DESCRIPTION_CLOSE_NOTIFY ALERT_DESCRIPTION_UNEXPECTED_MESSAGE ALERT_DESCRIPTION_BAD_RECORD_MAC ALERT_DESCRIPTION_RECORD_OVERFLOW ALERT_DESCRIPTION_DECOMPRESSION_FAILURE ALERT_DESCRIPTION_HANDSHAKE_FAILURE ALERT_DESCRIPTION_BAD_CERTIFICATE ALERT_DESCRIPTION_UNSUPPORTED_CERTIFICATE ALERT_DESCRIPTION_CERTIFICATE_REVOKED ALERT_DESCRIPTION_CERTIFICATE_EXPIRED ALERT_DESCRIPTION_CERTIFICATE_UNKNOWN ALERT_DESCRIPTION_ILLEGAL_PARAMETER ALERT_DESCRIPTION_UNKNOWN_CA ALERT_DESCRIPTION_ACCESS_DENIED ALERT_DESCRIPTION_DECODE_ERROR ALERT_DESCRIPTION_DECRYPT_ERROR ALERT_DESCRIPTION_PROTOCOL_VERSION ALERT_DESCRIPTION_INSUFFICIENT_SECURITY ALERT_DESCRIPTION_INTERNAL_ERROR ALERT_DESCRIPTION_USER_CANCELLED ALERT_DESCRIPTION_NO_RENEGOTIATION ALERT_DESCRIPTION_UNSUPPORTED_EXTENSION ALERT_DESCRIPTION_CERTIFICATE_UNOBTAINABLE ALERT_DESCRIPTION_UNRECOGNIZED_NAME ALERT_DESCRIPTION_BAD_CERTIFICATE_STATUS_RESPONSE ALERT_DESCRIPTION_BAD_CERTIFICATE_HASH_VALUE ALERT_DESCRIPTION_UNKNOWN_PSK_IDENTITY N) namedtuple)Enum)OPENSSL_VERSION_NUMBEROPENSSL_VERSION_INFOOPENSSL_VERSION) _SSLContext)SSLErrorSSLZeroReturnErrorSSLWantReadErrorSSLWantWriteErrorSSLSyscallError SSLEOFError) CERT_NONE CERT_OPTIONAL CERT_REQUIRED)txt2objnid2obj) RAND_statusRAND_add RAND_bytesRAND_pseudo_bytes)RAND_egdcCsCx<ttD].}|j|r tt|t|s r+)PROTOCOL_SSLv2ZSSLv2)PROTOCOL_TLSv1_1PROTOCOL_TLSv1_2zTLSv1.1zTLSv1.2win32)enum_certificates enum_crls)socketAF_INET SOCK_STREAMcreate_connection) SOL_SOCKETSO_TYPEz tls-uniquezECDH+AESGCM:ECDH+CHACHA20:DH+AESGCM:DH+CHACHA20:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+HIGH:DH+HIGH:RSA+AESGCM:RSA+AES:RSA+HIGH:!aNULL:!eNULL:!MD5:!3DESzECDH+AESGCM:ECDH+CHACHA20:DH+AESGCM:DH+CHACHA20:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+HIGH:DH+HIGH:RSA+AESGCM:RSA+AES:RSA+HIGH:!aNULL:!eNULL:!MD5:!DSS:!RC4:!3DESc@seZdZdS)CertificateErrorN)__name__ __module__ __qualname__rrrr r8s r8c CsDg}|sdS|jd^}}|jd}||krYtdt|n|su|j|jkS|dkr|jdnY|jds|jdr|jtj|n"|jtj|j ddx$|D]}|jtj|qWtj d d j |d tj }|j |S) zhMatching according to RFC 6125, section 6.4.3 http://tools.ietf.org/html/rfc6125#section-6.4.3 F.*z,too many wildcards in certificate DNS name: z[^.]+zxn--z\*z[^.]*z\Az\.z\Z)splitcountr8reprlowerappendrreescapereplacecompilejoin IGNORECASEmatch) ZdnhostnameZ max_wildcardsZpatsZleftmostZ remainderZ wildcardsZfragZpatrrr _dnsname_matchs&  " &rLcCs[|stdng}|jdf}xC|D];\}}|dkr4t||r_dS|j|q4q4W|sxc|jdfD]L}xC|D];\}}|dkrt||rdS|j|qqWqWnt|dkrtd|d jtt|fn;t|dkrKtd ||d fn td dS) a)Verify that *cert* (in decoded format as returned by SSLSocket.getpeercert()) matches the *hostname*.
